Letters Patent No. 95,189, dated September 28, 1869.

IMPROVEMENT IN LIQUID-METERS.

The Schedule referred toin these Letters `Patent and making part of the `same `vented newand useful Improvements in Water-Me ters;;and we do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings, andtothe lett-ers off reference-marked thereon.

The nature of our. invention consists in the arrangement and construction of 'the meter,'its several i parts being enclosed within ametalli'c case.'

i To enable` others skilledin the. art to make and use our invention, we will proceed to describe its coustruc` tion and operation. i 1

Figure lrepresents a perspective view of our4 improved water-meter, `with a part of the vshell removed. p i 4 Figures 2, 3, 4, and 5, represent details of theprin` Similar letters in responding parts.` p y In `the Vconstruction of o'ufrimprovedA device,` a represents the case or shell, into whichareplaced andsecured'the ,working-parts of thclsanie, this shell c heilig provided, at its bottom, with an oriiice, l), for the discharge-of the fluid or water meas-V ured.

Thevtop, or cover c, of this shell c, is provided with an opening', through whichpasses the inlet, or supply-pipe d,'which connects Vwith the top part of the plate c, this `plate e being connected to the bottom' "plate, or base j, by means of` sc1ews.

Formed in the centre of the 4plate e, on itsaunder side, is a concave recess, q, into whichyis ,piaced the strainer h, as shown ihr iig. 2 of the'dawings, 'its `through the meter fromthe supply-pipe el.

object being to prevent any sediment-.frompassing c v.nicely arranged, mounted, and so sensitive that the i is the. conductor, which is secured to the base j,

p and connects'with the concave recess g..

rIhis ,conductor-i Ais providedwith one or more spoutsjor conveyers j i,.the-y being locatedso as to i discharge and convey all the 'water or yfluid directly on to the body of thebuckets k L, which passes through the meter.` I i These buckets -li: la are formed straight or concave,

as desired, on the wheel l, as shown iu iigs. 1 and 3 of the drawings, which iscoustructed from a light and thin-metal, as will l.give suiiicieut strength to the same, necessary for` the required operation.

This wheell is secured to the shaft mf, which isv furnished with'hearings at eachend formed in suitable -he dihe'rent figures indicatecorto the 'underside of the plate f the other cud of said shaft'p passi-ng through the base f and plate e, which forms a bearing for the same, and receives the catchpinion q, which is secured `to the same.

4This catch-pinion q connects and gears into the `.catch-gear r, as occasion requires, which is provided witha quill, t, and mounted on a stud, s, whichstud is secured to the plate e, this quill t passing through the cover c of the shell `a., ou which is secured the pointer or hand u.

Formed on the cover c, directly in under this pointerl u, is a dial-face, which is suitably div-ided, figured, and marked inthe required divisions.

The conductor, as shown in iig. 4 of' the drawings, is provided with a regulating-valve, c, whiclrmay be worked, laterally, alternately, as occasion may require, by the operator, by aid of theadjustable screw w, the object of this valve c being to determine and fix the amount of' water discharged, so as to correspond with the figures on the dial.

Our improved device being constructed as herein described, and the several parts adjusted in "position,

is then ready for use. v

The water is then let into the supply-pipe d. From thence it passes through the strainer' It, thus arresting all particles of dirt or sedimentthat it may coutain; thenceit passes into and through the .conductor i, and discharged from the salue through the spouts j j on to the buckets 7c k, and thence through the dischargeforiice b.' .i

' The forceand weight of the water cause the'wheel lto revolve, in proportion to that force or weight,

which motion of the wheel lis communicated to the p ointer why means of the worin mand gear o, catchpinion q, and catch-gear r, the pointer u indicating on the dial the amount of water discharged from the orifice '5,3 the wheel l, with the buckets 7c k, being so light,

jleas't'action of water, being less orgreat on the same, will give corresponding action and motion to the wheel l,..w` l 1icl1is communicated vto the pointeru through the different devices, thus indicating or pointingout on the vdial the quantity of water that passes through the meter.

'Ihus we are enabled to furnish a meter which is compact, simple, cheap,"-and durable.

What we claim as our invention, and desire to. secure by Letters Patent, is- Y The arrangement and construction of the case a, cover c, plates e and f, strainer It, conductor i, with .one or more spouts jj, regulating-valve tv, and wheel Z, with bucketsk' k, allwhen combined and' operating as described and specified. i
